Why...

...there are jokes about "how many ??? does it take to change a lightbulb":

 Now scrutinise carefully the last tip. Two feet (both feet, unless you have more) and one hand on the ladder? Given that many homes now have fairly high ceilings, and we're talking about standard-sized ladders where you have to practically climb to nearly the top step, the only way to do that is to crouch (at the ladder's top) -- unless you are the acrobatic sort.

Assuming you are not acrobatic, do you think you can reach for the lightbulb in that precariously crouched posture? You read it here first why there are so many "changing lightbulb" jokes!

But, seriously, how do people change the lightbulb at home when using the ladder? People like me climb to a suitably safe height -- preferable with someone else present in the room -- and lean both feet against the ladder. Both hands are then free to deal with the blown lightbulb.

...you should ignore a silly tip on consumer bargaining power, like this one:

Again, think carefully about Tip #6. If you don't absolutely have to buy something, why are you there? How then does walking away make you feel you have the power, and therefore feel better?

There's even a scary Haha. Can you spot it? (this segment is from a recent issue of ST's Mind Your body).

...ASEAN leaders and their "Plus Three" partners should stop this annual photo-op pose:

Don't you think they look silly playing this "pass the electric current" thingy? And why is there a gap between the leaders of South Korea and Brunei?

Heard on the radio

Finally, this one is a gem. A dietitian was on the radio (FM 93.8) telling listeners to go easy on the sugary stuff. Her name: Candy!
